A. Rs. 72.20

B. Rs. 72

C. Rs. 85

D. Rs. 7.20

Solution:

Marked price of article = Rs. 80

\begin{aligned} Two successive discount \\ =  5 + 5 - \frac{5 \times 5}{100} \\ = 10 - 0.25 \\ = 9.75 % \\ Discount of article \\ =  9 .75%  of 80 \\ = \frac{9.75}{100} \times 80 \\ = Rs . 7 .80 \\ Selling price of article \\ = 80 - 7.80 \\ =  Rs . 72 .20 \end{aligned}
